COLLAPSBLE BOX.

Specification of Letters Patent.

Patented March 12, 1907 'ipplication filed December 13, 1906. Serial No. 347,579.

To (L7/Z whom/'it may concern:

Be it known that I, DANIEL F. FRIEDHEIM, a citizen of the United States, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Im rovements in Collapsible Boxes, of which the following is a specification, reference being had therein to t e accompanying drawings, in which- Figure 1 is a perspective view ofthe box with the cover 1n position, the cover being partly broken away; Fi 2, a perspective view of the box with t e cover removed; Fig. 3, a perspective view of the box partly co lapsed; Fi .4, a similar view of the box completely co lapsed, and Fig. 5 a detail vertical sectional view on the line V V of Fig. 2. One of the objects of the invention `is to rovidela collapsible box with permanent ocking means, whereby said box may be held in its extended or open position while being filled. A- further object of the invention is to so construct the box that it may be collapsed to its smallest extent, provision being made for the locking devices which-hold it in its extended position, so that said devices will not interfere with the close folding of the box.

Referring to the various parts by e nu'- merals, 1 designates the bottom of the box, which is preferabl rectangular, 2 the solid or unfolded ends t ereof, and 3 the collapsible sides. The sides and ends are connected to each other at the corners of the box and to the bottom by flexible connections, so that they may fold inward and down on the bottom. The sides are creased or folded from their lower corners to a point along the up er edges thereof, said folds being so made t at the ends will have a tendency to normally fall inward. Each side is formed with two creases or folds 4 and 5, each fold extending from one lower corner of said side upward to the up er free edge of the side at an angle of fortyve degrees, formin three panels 6, 7, and 8. The result of this is that when the sides and ends are folded inward and down to the bottom of the box the upper thus formedhas a" tendency to fall inward to,l

its collapsed position.

To ho d the box in its extended position, I secure to the outer side of the middle panel 7 of each side a locking-bar 10, said bar eing pivoted to said panel near its upper' edge and midway between the panels 6 and 8. This bar is'long enough to extend across the folds 4 and 5 when it is arranged-in a hori.

zontal position or substantially parallel withA the upper edge'of the side and to thereby prevent theinward folding of the sides. I prefer to pivot the bar on the panel 7Iby means of an eyelet 11 passing through the bar and through the panel, and I prefer that the bar should 'be long enough to extend'about halfway across the panels 6 and 8, asn that length of the bar gives a substantial support for the sides. The eyeletholes form convenient apertures through which may be passed the strings 12, by which the cover 13 1s secured inplace. f

.To collapse the box, the locking-bars 10 are brought to a vertical position between the panels 6 and A8. The sides will then fold inward and downward to the bottom of the box. The .locking-bars 10 will lie side by side in the channel between the free edges of the end pieces of the box. It will be noted that there must be a space between the upper ends of the folds'4'and 5 in the sides in order that the locking-bars will project beyond the free edges of the sides when they are in their folded positions. To obtain this, the sides of the box must be longer than double their height, as will be manifest.

It will be readily understood that other forms of locking-bars may be employed, and I do not Wish to be limited` to the precise form shown in the drawing.

Having thus described my invention, what I claim as new, anda desire to secure by Letters Patent, is

1. A collapsible box comprising an uncreased bottom, uncrease'd ends lexibly connected at their lower edges to the op osite edges of the bottoni, creased or folde sides flexibly connected at their lower edges to Iopposite edges ofthe bottom and at their vertical edges to the adjoining vertical edges of the ends, each of said sides being folded to formv three panels and normally tending lOO IOS

' substant'ally of the si e, an of such width that when it is VJfree edge ofthe sides a suitab e distance from each other, and a locking-bar pivoted to the outer side of theI central panel of each side and of such length as to extend across the folds between the anels when said bar is arallldl with the upper. edge perpendicular to the edges oi the sides it will ie between the two end-panels and not en? gage either of them.

' 2. A collapsible box comprisin a bottom, ends flexibly connected at their lgower edges to opposite edges oi' the bottom, sides flexibly connected to the bottom and to the adjoining Vertical. edges of the ends, said sides beingfolded toform three panels, said folds extendin upward rorn'the lower" corners of the si es at an angle of' forty-five degrees, said sides being longer than double their' height, whereby the folds at their u per ends will be separated a short distance om each other, and locking-bars pivoted to the outer surfaces ofthe sides at the centers ontk the middle panels and adaptedto lie, wheny the box is collapsed, inthe channel be-iwv'eenly the edges of the'ends ofthe box and the edges ofthe end panels of thesides.

3. A collapsible box comprisin a bottom, ends iiexibly connected at their ower edges to opposite edges of the bottom, sides flexibly connected to the bottom and to the adjoining vertical edges of the ends, said sides being folded to form three panels, saidolds extendin upward from the lower' corners vof the sie's at an angle of forty-five degrees, said sides being longer than` double their height, whereby the folds at their u per ends will be separateda short distance om each other, and loclrjngfbars pivoted to the outer surfaces of the sides at the centers ofthe middle panels and adapted to lie, whenfthe box is collapsed, in the channel between the edges of the ends kof the box and the edges of the end panels of the sides,a cover, and strings attached to the middle anely of the sides Vand` adapted to -secure t e cover in 'place and to assist inholdingthe box in its extended positions. i 4
